How and When to Plant Elephant Ear Bulbs
Elephant ear is the common name for several groups of perennial plants, including Colocasia esculenta (taro) and Alocasia macrorrhizos (giant elephant ear), the two types most familiar to gardeners.
These vibrant tropical plants are known for their spectacularly large leaves, which give them their name. Gardeners love them for their showy foliage, tropical feel, and quick growing time. They make a beautiful addition to any garden and can be grown as annuals or perennials.
Though there are multiple types of elephant ears, they are all planted the same way. We’ll walk through the steps and get you set up for the biggest, brightest elephant ears in your garden or in containers.
Before You Start: Prep for Success
Before you dive into planting your elephant ear bulbs, it’s essential to get to know the plant, determine what type you want in your space, and plan ahead for optimal care.
The first decision you need to make is whether to choose taro or giant elephant ear. This depends on how much available space you have in your garden and how large you want the plant to be. Taro plants typically grow 3–6 feet tall and have leaves 2 feet in length. Giant elephant ears can grow up to 15 feet tall, with leaves 6 feet long and 4 feet wide.
Once you’ve made that decision, you’ll need to settle on a variety. While elephant ears are most commonly seen in a bright green color, there are many other variations that can add diversity to your landscaping.
Whichever you choose, you will follow the same planting instructions. All elephant ear bulbs are planted the same way and require the same conditions to flourish.
When to Plant Elephant Ears
Elephant ears are tropical plants, which means that you should always wait to plant the bulbs until after the final frost of the season. The tubers won’t grow unless the soil is at least 65°, which means late June for most northern climates.
To determine whether you will grow elephant ears as perennials or annuals, you will need to know your hardiness zone. In zones 9-11, elephant ears can be grown in the ground year-round, but in zones 3-8, where it’s cooler, you have to plant them in the spring as annuals. They will not survive freezing temperatures.
Elephant ears will grow in either sun or shade, but if you plant them in a location with adequate sunlight, make sure they can get shade around midday.
What Kind of Soil to Use for Elephant Ears
Elephant ears are known in the gardening community as “big eaters,” meaning they require a lot of fertilizer to grow and thrive. They do best with rich, moist soil mixed with organic matter, such as compost.
They also prefer a soil pH between 5.5 and 7.0. If you need to change your soil’s pH, you can add lime to raise it or sulfur to lower it.
Before you plant your bulbs, prepare the garden bed by turning the soil and digging a hole to a depth of 8 inches. Make sure to remove any grass, stones, or other debris from the soil, then level out the bed when you’re finished.
